2 Claims.

The object of the present invention is to provide a smokers pipe consisting of a bowl and bowl stem, a bit, and threaded connections intermediate the bit and the bowl stem enabling a tight fit between the said members and at the same time enabling the bit to be turned in a given direction, without changing the tight fit between the bit and the bowl stem, in order that the bit may be accurately positioned, with the flattened portion of the bit disposed at a right angle to the vertical axis of the bowl.

The specific object of the invention is to provide a smokers pipe of the stated character which will have a predetermined frictional resistance to the stated adjustment of the bit relatively to the bowl, which will maintain that condition, which will be capable of easy assembly, and which will be of low cost.

The invention will be described with reference to the accompanying drawings, in which:

Figure 1 is a top plan view of a smokers pipe which may incorporate the invention, the bit having been adjusted to a proper position and with a tight fit relatively to the bowl stem;

Figure 2 is a view similar to Fig. 1 showing the bit having been turned to a tight fit relatively to the bowl stem and yet out of proper position, requiring rotation of 90 and to the position of Fig. 1;

Figure 3 is an enlarged fragmentary longitudinal section taken on the line 3-3, Fig. 1;

Figure 4 is a composite enlarged view showing the bit and bowl stem connecting elements separated and in proper line position for assembly.

Referring to the drawings I have shown at I the bowl of a smokers pipe, the latter carrying a bowl stem 2, the bit being indicated at 3 and the flattened mouthpiece end of the bit being shown at 3x. In Fig. 3 the bowl stem and bit elements are shown connected by the means now to be described.

It will be seen that there is threaded into the aperture 2:1: of the bowl stem a flanged connector receiving sleeve, the exterior of the sleeve 4 merging at its outer end into the annular flange 4x, the latter preferably being of the same diameter as that of the outer end of the bowl stem so as to form a facing therefor. The bit is formed with a smoke passageway at 5, Fig. 3, which merges into an enlarged chamber. In the said chamber there is frictionally held the knurled head I of a connector element having a tubular extension 8. Rotatable on tubular extension 8 is a sleeve 9 having a threaded extension Ill which is adapted to be received by the internally threaded flange connector receiving sleeve 4.

It will be seen by reference to Fig. 3 that the outer end of sleeve 9 is formed as a cup and that it receives an axially apertured disk I I. This disk may be of rubber or other material adapted to exert frictional pressure intermediate the inner wall of the cup and the tubular extension 8 or intermediate the cup and the head I.

The tubular extension 8 extending from the knurled head 1 receives members 9, l0 and II and also extends, in the embodiment shown, slightly beyond the end of the externally threaded member 10, being flared at the exterior of member 10 so as to hold the entire connector assembly. Thus by the extent of the flaring operation and the pressure between the walls of the cup of member 9 and the knurled head 1 as imposed upon the disk H, a predetermined degree of frictional force will be obtained in order to control the force required to turn the bit in clockwise direction after it has been tightly fitted to the bowl stem by like rotation of the bit.

It will be understood that flared end 1a: of the tubular extension 8 of the knurled head 1 is not essential, although it is desirable. Thus the tubular extension 8 may be so proportioned to the interior diameter of member II] as to require merely force-pressing.

Usually the bit 3 will be made of hard rubber or equivalent plastic material. In such case, as customary with bowl stem-bit connectors, the chamber end of the bit will be heated so that its inner wall will be softened. Also, as customary, the diameter of the connector-receiving chamber may be slightly less than the diameter of the knurled head 1 and member 9. With the chamber wall thus softened the connector assembly is pressed into the chamber, which action results in some displacement of the softened rubber or other plastic, the latter entering the knurled depressions in the head I, and also contacting with the smooth surface of the connector member 9. When the bit is cooled the connector element 1 will be firmly anchored to the bit, with the exception that by reason of the smooth surface of member 9 it will not be held by the bit. Therefore the bit and members 1 and 8 as a unit may be rotated relatively to connector elements 9 and I0 after the entire pipe assembly is effected, and with a pre-controlled force.

It will be understood that various modifications may be made in the form and arrangement of the elements constituting the embodiment illustrated in the drawings without departing from the spirit of the invention.

Having described my invention, what I claim and desire to secure by Letters Patent, is as follows:

1. A smokers pipe consisting of a bowl, a bowl stem integral with said bowl and having a threaded aperture in that portion that is disposed away from the bowl, a bit having a cavity communicating with a bit channel, and a connector consisting of a first exteriorly threaded sleeve having an router flange, said "flange'having a beveled shoulder adjacent an axial bore and adapted to be screwed into said bowl stem aperture, said first sleeve being interiorly threaded, a second exteriorly threaded sleeve having .an outer cup shaped portion, said portion having an inwardly disposed beveled shoulder; said second";

through said second sleevetoa, point slightly be.

yond the threadedextensionof the said second sleeve, said knurled head andysaid cup shaped channel of said second sleeve to effect a contact between the cooler flange and the rim of the tubular'extension.
